CALORIC STREET-ROLLER.

The Schedule referred.V to in these Letters Patent and making part oi the same.

To all whom it may concern.:

Be it known -that I, M. J. BEXDALL, ot' the city, county, aud-State ot' N ew York, have invented anew and ilnprov'ed Calorie Street-Roller; and I do hereby declare fthe following?r to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawing, forming part. ot' lthis speeilication, in which drawing- Figure l represents'a horizontal centra this invention. l

Figure 2 is a transverse section ofthe saine.

This invention onsists in the arrangement' of a fire-grate in the interior of a street-roller, in such a manner, that by means of a tire built on said grate,

section of the roller van be heated and kept het while it is being used, and thereb)Y the @eration ot' rolling eonerete walks or pavements materially facilitated.

In the drawing, the letter A designates a. streetmller iliade in the ibi-n1 oi'an annular' c vlinderot castirnn, or an)` other suitable. material, in the usual nlau.-

ner.

In the interior of this hollow' cylinder, I place a-tire grate, B, which, by preference, will he Iliade in the form ot' a semieylimler, and suspended freni gudgeons, a, projecting from the centres ofthe open heads of the rollers, as shown in the drawing.

The bottom and ends ofthe seini-oyIimh-icai grate B i are perforated or made in the form of slats, so that the air has i'ee access to the fuel on the grate. The roller may be provided with movable caps which can be inserted into the ends, so thatv the heat of the tire may` be eontined to the interior of' the roller when desirable. f 1

One or both ofthe open heads of the roller will be so constructed that the saine can be taken out for the purpose ot' facilitating the operation ot' insertingor removing,r the grate.

By this arrangement ota tire-grate in the interior of a street-roller, such roller `can be readily heated and kept hot while the same is being used, and thereby inueh time andlabor are saved, particularly in rolling' pavements or walks made ot' Concrete, or any other eonipmuid which requires heat while being; rolled.

What I claim as new, and desire to secur'eby Letters Patent, is

The arrangement of a tire-grate in the interior of a street-rol1er, substantially as and i'or the purpose set forth.

This specitation signed h v me, this lit-h day of October, 1865).
